Abstract
The utility model discloses a current mutual inductor. Nameplates on existing products and casings of the products are fixedly connected by rivets or bonded by adhesives, which has the advantages that the nameplates can be easily romoved and replaced, the fraudulent use of electricity can be carried out. The outer edges of nameplates of the utility model are provided with flanges which are backwards bent; the flanges of the nameplates are inserted into a casing which is formed by that insulating materials are cast; the nameplates and the insulating casing are connected into integration, so the nameplates can prevent from removing and replaing, and the utility model can prevent the possibility of carryingout the fraudulent use of the electricity.
Description
The utility model belongs to a kind of current transformer.
Current transformer is the big electric current in the main circuit that flows through according to primary side, induces the little electric current of certain ratio at secondary side, realizes measuring and the electric device of relaying protection for instrument.Nameplate is set on current transformer, and the electrorheological of indicating this device such as compares at the major technique number, for correctly installing and using.The right nameplate of the existing manufacturer of this series products with continue to use that rivet is fixed connecting of product shell or with the viscose glue bonding, this connection is insecure, is prized by the people easily always.According to the power department reflection, the somebody prizes the original nameplate of instrument transformer, changes the nameplate of different electrorheological ratios and steals.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of nameplate to connect with product shell firmly, and nameplate is difficult for being prized the current transformer that falls to be replaced.Prevent to implement to steal the possibility of electricity to change nameplate.
For achieving the above object, the technical solution adopted in the utility model is: current transformer comprises the current transformer body that is made of inductive iron core and coil windings, the housing that pours into insulating material of sealed body and be fixed on the nameplate that front on the housing indicates main technical details such as electrorheological compares, the crimp of the outer rim of described nameplate oriented back side bending, the nameplate bottom surface is close to the surface of the housing that described insulating material is cast into, crimp embeds in the insulation shell, fuses with housing.
Nameplate is placed the mould precalculated position, and with insulating material cast housing the time, crimp just embeds in the insulating material, fuses with housing.
Owing to adopted the crimp of nameplate to embed structure in the housing, reached nameplate with housing fuses securely, the relative housing of nameplate is difficult for being prized the purpose of falling to be replaced.
Below in conjunction with the drawings and specific embodiments the utility model current transformer is described in further detail:
Fig. 1 is the nameplate configuration structure schematic diagram of top wiring circular hole instrument transformer.
Fig. 2 is the nameplate configuration structure schematic diagram of bottom wiring circular hole instrument transformer.
Fig. 3 is the nameplate configuration structure schematic diagram of coil type instrument transformer.
Fig. 4 is the nameplate configuration structure schematic diagram of square hole instrument transformer.1, current transformer body 2, insulation shell 3, nameplate 4, crimp
Execution mode of the present utility model, as Fig. 1,2,3,4, current transformer comprises the current transformer body (1) that is made of inductive iron core and coil windings, the housing (2) that pours into insulating material of sealed body and be fixed on the nameplate (3) that front on the housing indicates main technical details such as electrorheological compares, described nameplate the crimp (4) of outward flange oriented back side bending, the nameplate bottom surface is close to the surface of described insulation shell (2), crimp (4) embeds in the insulation shell, fuses with housing (2).
Claims (1)
1, current transformer of the present utility model, comprise the current transformer body (1) that constitutes by inductive iron core and coil windings, the housing (2) that pours into insulating material of sealed body and be fixed on the nameplate (3) that front on the housing indicates main technical details such as electrorheological compares, it is characterized in that: described nameplate the crimp (4) of outward flange oriented back side bending, the nameplate bottom surface is close to the surface of described insulation shell (2), crimp (4) embeds in the insulation shell, fuses with housing (2).
